I don’t know what’s the deal between the Maasai and the Swiss, but here’s an interesting
shoe training tool from Switzerland called Masai Barfuss Technologie (MBT) by a company that goes by the name of Swiss Masai (as seen on polylux and other channels):
"Using a multi layered sole, MBT® transforms flat, hard, artificial surfaces into natural, uneven ground. Much like walking in sand, the unique uplifting lever spring action of the MBT® sole challenges the core strengthening muscles to be more active. This reactive, more supportive muscle action creates good posture and increases shock absorption for all the joints, significantly reducing muscular-skeletal compression."
Yaani, this modern flip-flop costs 179,- EURs (~ 215 US$)…
